7th 6L.7 / 6th #15 [ENDORSED]

[Saachi_Kotia_4E]

can someone show me their work or explain how to do this problem? I'm confused on all three parts. it's 6L.7 from the 7th edition, and 15 from the 6th edition.

You need to come up with two half reactions that sum to the overall reaction. The best way might be to choose one species from the reaction and write down a reduction reaction that includes it. Then subtract (reverse and add) this reduction reaction from the original reaction to get the corresponding oxidation reaction. If both of these reactions have reduction potentials, then you can calculate the standard cell potential and therefore the ∆G° of the reaction.
